MEASURING DEVICE.

Specification of Letters Patent.

Patented Jan. 16, 1906.

To all whom, it may concern.-

Be it known that we, HENRY RAAB and JACOB M. WOLFSON, citizens of theUnited States, and residents of the borough of Manhattan, city, county,and State of New York, have jointly invented a certain new and usefulMeasuring Device, of which the following is a specification.

This invention relates to a measuring device, and its organizationcomprises, essentially, a cylinder with a piston therein, means to movethe piston to various positions, and a valve device to allow the fillingand emptying of the cylinder.

The invention is exemplified in the accompanying drawings, in whichFigure 1 represents a front elevation of the invention attached to areservoir. Fig. 2 shows a partial plan view and section of Fig. 1 on theline 00 as. Fig. 3 is a partial end view and section of Fig. 2 on theline as as. Fig. 4 represents an enlarged fragmentary portion of Fig. 1.Fig. 5 shows a side view and partial section of Fig. 4 on the line m 90To a reservoir A is fastened a cylinder B by means of the bracket B, andin which is located the piston C, with the piston-rod C connected to theyoke D. The latter is supported in the guides E, that extend from thecylinder B and have connected therewith the column E by means of thebolts e. The yoke D has formed at its top and bottom ends the slides D,that bear against the guides E, and the upper guide has an o ening FF,through which passes a bolt or stu D that is carried by the yoke D andhas a wing-nut D On one of the faces of one of the guides E is marked ascale E constituting with the upper slide an indicator for the positionof the piston.'

A bracket F extends from the cylinder B and has formed therewith thejournal-bearing F, that carries the shaft G, with the crank-wheel G andhand-wheel G From the boss G of the crank-wheel G extends the crank-pinH with the collar h, the said crankpin-passing through the opening D ofthe yoke, so that the end faces of the collar h and boss Gr straddle thesaid yoke.

To the reservoir A is clamped the cylinderinlet conduit I, which leadsto the inlet-valve chamber J. The said chamber has formed at its lowerend the valve-seat J for the inletvalve J" with the spindle J. A bonnetK fits the said inlet-valve chamber J and has formed therein astuffing-box with the gland K. Below the port formed by the valveseat Jis the conduit J leading into the cylinder B at one end thereof. Fromthe lower side and at one end of the cylinder the outlet-conduit Lconnects with the outlet-valve chamber M, similar in construction to thechamber J. It has formed therein the valveseat M for the outlet-valve Mwith the spindle M A bonnet N fits the said chamber M and has formedtherein a stuffing-box with the gland N. Below the port formed by thevalve-seat M is the outlet-conduit M 7 A bracket P extends on the top ofthe cylinder B and has extending therefrom arms with the guides P P forthe spindles J and M respectively. The spindle J carries at its top endthe loop J and the splndle M the loop M In the loop J is threaded thescrew J and the loop M carries the screw M, the said screws being attimes made relatively larger than shown in the drawings. The said loopsare engaged by the ends of the beam R, that is secured to the shaft R,supported in the journal-bearing R extending from the bracket P.Fastened to the shaft R are the arms S and T. The ends of the screws Jand M can be made to bear against the ends of the arm R by properlylocating them in the loops J and M", respectively. The arm S hasconnected therewith the handle S, on which is carried a spring-latchwith the plunger S and hand-lever S Openings p p p are formed in thebracket P to allow the clamping of the arm S in different angularpositions by the engagement of the plunger S with one of the saidopenings p 10 f. The arm T. engages a sleeve T, that is ournaled in theend of the arm V, which is connected with the plug V of the vent-valve VThe plug V has the through-port V and the cross-port V at right anglesthereto. The valve is supported on the pipe W, leading from the cylinderB, and carries the vent and measuring pipe W, generally made of glass,andr a secondary outlet for the valve is shown at The valves in thevalve-chamber are generally pistonvalves, as shown, although other formsof valves may be used.

To use the invention, a fluid or other material which is to be measuredis placed into the reservoir A. When the arm S is in the posi tion shownparticularly in Fig. 3, the valve J is on its seat and prevents any ofthe fluid or material leaving the reservoir A and entering the cylinderB. When a fluid, .&c., is to be as a vent is also an overflow-pipe.

taken out of the reservoir and measured, the arm S is moved to the left,as shown by the arrow in Fig. 3, by disengaging the plunger S from theopening p and engaging it with the opening 10, which will raise thevalve J 2 to allow the fluid, &c., to enter the cylinder B through theconduit J 4 and seat the valve M on its seat M to prevent the materialleaving the cylinder before being measured. At the same time the lever Twill be moved to open communication between the cylinder B and theatmosphere through the vent-pipe W. The hand-wheel G is then turned tobring the piston to the required position (indicated by the position ofthe slide D on the scale E to fill it with a specified amount ofmaterial or fluid, and it can be clamped in position by the wing-nut D.As the fluid or other material enters the cylinder the air escapesthrough the vent-pipe W, and when the cylinder has been filled it willbe indicated in said pipe W. As soon as the material shows above thevent-valve V the arm S is moved back to the position shown in Fig. 3,which raises the valve M from its seat M and closes the valve J with itsseat J and at the same time closes communication between the cylinder Band pipe W and opens communication between the opening V and the insideof the said cylinder. This latter disposition of parts allows theemptying of the cylinder with a vent through the opening V 5 andprevents the material escaping which may have risen in the pipe W. Itwill be noted that when the cylinder B is being filled the vent V isclosed, and the pipe W besides acting After the cylinder has beendrained it is ready for a second operation, and if the same amount ofmaterial is to be taken from the reservoir the piston is not moved,otherwise it is moved and clamped in a new position. Should it bedesired to drainthe reservoir without measing the material, the arm S islocked in a vertical position and the screws J and M brought to bear ina position to raise both of the valves J and M the arms V and T beingdisconnected, so as to keep the through-port V in a position to allowavent to the cylin- The invention may be modified by dispensing with thestuffing-boxes of the valve-chambers J and M and making appropriateguides for the valve-spindles J and M Openings may be made in the upperportions of the valve-chambers to allow the air to escape and avoidcompression therein.
